You have just started to load Dicyclopentadiene to 5 port and starboard cargo tanks, but no cargo seems to be coming into the tanks. What will you do?

Stop cargo - notify the Duty Officer and / or the terminal dependng on the agreed communication procedure. Re-check the lines, valves and connections carefully, bearing in mind that there might be a build-up of pressure. Advise as appropriate.

Open the main lid on the tank and use a flashlight to try and see if there is a problem with the pump or line inside.

Carefully slack the bolts back on the connections, working initially on the off-shore mainifold, to determine how far the pressure extends in the ship's pipeline system, to determine which valve is giving the problem.

Re-check all valves. Just say nothing and open it, if one is found closed.

When bunkering through the port side of the bunker manifold what action should be taken with the valves on the starboard side of the manifold prior to bunkering operations commencing?

Just check that the valves are closed.

Blank flanges should be fitted to the closed starboard side manifold valves.

As well as having temperature sensors located in the cargo holds some reefer vessels are also fitted with ethylene sensors. Why is it useful to have information regarding the ethylene content in a reefer vessel cargo hold when carrying fruit cargoes?

The ethylene content must be maintained to help ripen the fruit during the sea voyage.

Some fruit cargoes are sensitive to ethylene and the quality of the cargo can deteriorate as they may over-ripen.

The ethylene content can be used as a guide as to when air change fans need to run.

The ethylene content is beneficial to perishable cargoes in transit so the content needs to be monitored in case the level falls.

During maintenance of a piston rod stuffing box on a large, slow speed diesel engine it is usual to measure the butt gaps between the sealing ring and scraper ring segments. What would be the effect of these gaps being too small?

If the gaps are too small they could close due to the radial wear of the rings before the next scheduled overhaul preventing the rings from contacting the piston rod and sealing it.

If the gaps were too small then no oil could pass up the piston rod to lubricate the sealing rings.

If the gaps are too small the rings could score the piston rod.

If the gaps are too small then the flow of scavenge air through the gland would be reduced and the gland would overheat.

Why is is especially necessary to continue to ventilate the tank and to continuously monitor the atmosphere when working inside a cargo compartment which still contains vegetable oil residues?

For a tank which has contained vegetable oils, if it is continuously ventilated an Enclosed Space Entry Permit is not required. However, for anyone entering the compartment without a permit in place, they must carry an oxygen meter which continuously monitors the atmosphere.

Forced ventilation will create a hard "skin" on the residues, making them safer to stand on. Testing the atmosphere will indicate when this skin has formed, as no further vapours will be released.

Vegetable oils are commonly washed using very hot water. Forced ventilation will make the temperature inside the compartment better to work in. Monitoring the atmosphere will indicate if the humidity is increasing.

Because the decomposing residues continue to release hazardous gases, reducing the levels of oxygen in the tank and making the atmosphere potentially dangerous.

Earlier reefer vessels designed and built for liner trade usually had two or three tween decks approximately 2 to 2.5 metres in height and deep lower holds approximately 4 to 5 metres deep.

The increased proportion of chilled as opposed to frozen cargoes that are carried.

There is an almost universal use of standard height pallets.

High-level alarms are always switched on during loading operations. Is it necessary to have them switched on during discharge operations on a chemical tanker?

The only way a high level alarm will activate during discharge is as the set level is passed as the tank empties. It is therefore of no value to have them switched on.

No, the alarms are only of value and significance for an increasing liquid level such as is found during loading.

Yes, there is still a risk of overflow if several tanks are connected to a common line system.
